Odd RL-15 experience

So I decided to try out RL-15 instead of my usual Varget for a possible match load (.308 175 SMK, CCI BR-2, Lapua case, 2600 fps). I noticed after a few shots that instead of the sharp 'pop' muzzle blast sound I am used to hearing when using Varget, it was more of a slightly drawn out 'phht' kinda sound. Velocity and accuracy were spot on, but something just seemed different. Am I imagining things or has anyone else ever noticed something similar with RL-15?

I also switched over from Varget to RL-15, but I can't say I have noticed anything different about the sound.

I can't speak directly to the difference between Varget and RL-15, but every time I try different powders in any gun the muzzle blast is different.

The most dramatic switch I've seen is between H380 and IMR3031 in my 15" Encore. H380 has a tremendous concussive blast and a flash so bright it's clearly visible in direct sunlight. 3031 has far less concusion and no visible blast. This is with otherwise identical components.

pop or pphhtt they are both excellent recipes.I do not have the software peetzakilla has,but you may find the Re-15 has a 100% burn and the Varget has a 97% burn in the bbl.Just a guess.
Were you shooting at the same range/firing point? Echo/accoustcs?

I can tell the difference in muzzle blast between various powders also when testing loads.

Strangest thing I have noticed about RL15 is that in 220 Swift, all other things being equal, RL15 will consistently stretch cases less.
